Abstract
The utility model discloses a microchannel heat exchanger with a serpentine heat exchange tube. The left and right ends of an upper guard plate and a lower guard plate are fixed on a left guard plate and a right guard plate respectively. The two sides of the serpentine heat exchange tube are fixed on the left and right guard plates respectively. Two orifices of the serpentine heat exchange tube are communicated with an upper collecting pipe and a lower collecting pipe respectively. The upper and lower collecting pipes are fixed on the left or right guard plate. Fins are fixed on the serpentine heat exchange tube. The serpentine heat exchange tube is a flat tube made from an aluminum alloy material. A tube body of the serpentine heat exchange tube is separated into a plurality of microchannels by a plurality of separation plates. The upper and lower collecting pipes are both provided with a refrigerant inlet and a refrigerant outlet. By the microchannel heat exchanger with the serpentine heat exchange tube, the consumption of copper resources is decreased, the emissions of pollutants are reduced, and the effects of energy saving and emission reduction are achieved.
Description
Technical field:
The utility model relates to technical field of heat exchangers, more specifically to the employed micro-channel heat exchanger of freezing and refrigeration air-conditioning.
Background technology:
The copper pipe aluminum fin heat exchanger is adopted in fields such as present domestic freezing and refrigeration more, uses expanding joint process to fit to reach the purpose of heat exchange by copper pipe and aluminium fin.Its weak point is: 1, copper pipe resource-constrained, price is also high, uses copper pipe to cause the copper resource nervous as heat exchanger tube in a large number.2, copper pipe aluminum fin expanded joint mode heat-transfer effect is poor.3, the product heat exchanger tube adopts pipe, and the pipe aperture is bigger, causes that to be discharged into airborne cold-producing medium more.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art, and a kind of snakelike heat exchange tube micro-channel heat exchanger is provided, and it reduces the consumption of copper resource, has reduced the discharging of pollutant, has reached the effect of energy-saving and emission-reduction.
The technological solution of the utility model is following:
A kind of snakelike heat exchange tube micro-channel heat exchanger; Comprise snakelike heat exchange tube, fin, go up header and lower header, two ends are separately fixed on left backplate and the right backplate about upper guard board and following backplate, and two limits of snakelike heat exchange tube are separately fixed on left backplate and the right backplate; Two mouths of pipe of snakelike heat exchange tube connect header and lower header respectively; Last header and lower header are fixed on left backplate or the right backplate, and fin is fixed on the snakelike heat exchange tube, and snakelike heat exchange tube is the flat tube of aluminum alloy material; The body of snakelike heat exchange tube is isolated into several microchannels by several shims, is provided with cold-producing medium on last header and the lower header and imports and exports.
Said fin is an aluminium alloy ripple bar, and two ends up and down of fin soldering respectively are fixed on the snakelike heat exchange tube.
Said snakelike heat exchange tube is one, two or three.
The beneficial effect of the utility model is:
1, the utility model adopts full aluminum, materials still less, and there is not potential difference in same material, prolonged life of product greatly, thereby reduced the consumption of resource than copper pipe aluminum fin heat exchanger.
2, flat tube adopts welding manner to be connected with fin, and is better than copper pipe aluminum fin expanded joint mode heat-transfer effect, thereby reduces the waste of the energy, increases the Energy Efficiency Ratio of product greatly.
3, the product heat exchanger tube adopts flat tube, and interstitial hole is less, compares the copper pipe aluminum fin heat exchanger and can reduce by 50% refrigerant charge, and charging amount has lacked and is discharged into airborne cold-producing medium relatively and also can reduces.
